這使先導(dǎo)閥襯套（15）中的控制端口被pvp（14）上的平臺(tái)覆蓋。10.輸出軸（6）和動(dòng)力活塞（7）的運(yùn)動(dòng)停止在新的燃料減少位置，該位置是在負(fù)載減少的情況下以選定的速度設(shè)置運(yùn)行原動(dòng)機(jī)所需的。再次增加負(fù)載，假設(shè)原動(dòng)機(jī)以一定速度運(yùn)行。飛錘處于垂直位置，先導(dǎo)閥柱塞居中。當(dāng)負(fù)載增加并保持相同的燃油設(shè)定值時(shí)，負(fù)載增加會(huì)導(dǎo)致速度下降。這將生成以下調(diào)速器運(yùn)動(dòng)序列：1。隨著速度的降低，飛錘（2）的離心力減小，并且反向的減速器彈簧（26）的力現(xiàn)在大于飛錘（1）的離心作用力。2.飛錘（2）向內(nèi)傾斜，降低調(diào)速器桿（4）和浮動(dòng)桿（18）的右端。3.這降低了先導(dǎo)閥柱塞（14），打開了旋轉(zhuǎn)襯套（15）中的控制端口。壓力油通過控制端口釋放到動(dòng)力活塞（7）的底部。
當(dāng)負(fù)載減少并且保持相同的燃油設(shè)定值時(shí)，負(fù)載減少會(huì)導(dǎo)致速度增加。這會(huì)產(chǎn)生以下動(dòng)作序列：1。隨著速度的增加，飛錘（2）的離心力增加，克服了相反的調(diào)速器彈簧力。2.飛錘（2）向外傾斜，升起調(diào)速器桿（4）和浮動(dòng)桿（18）的右端。3.這將升高先導(dǎo)閥柱塞（pvp）（14），打開旋轉(zhuǎn)襯套（15）中的控制端口。機(jī)油從動(dòng)力活塞（7）的底部釋放到油底殼。4.作用在動(dòng)力活塞（7）頂側(cè)的壓力油迫使其向下，并使輸出軸（6）沿減少燃料的方向旋轉(zhuǎn)。5.來自輸出軸（6）的連桿降低補(bǔ)償調(diào)節(jié)桿（5），補(bǔ)償調(diào)節(jié)桿在支點(diǎn)（24）處樞轉(zhuǎn)，抬起大補(bǔ)償活塞（21）。6.因此，對(duì)小補(bǔ)償活塞（20）的腔室施加吸力，從而降低浮動(dòng)桿（18）的左端。7.依次降低pvp（14），關(guān)閉控制端口（16）。8.當(dāng)油底殼油從油底殼流經(jīng)針閥（22）進(jìn)入補(bǔ)償活塞組件（20和21）時(shí)，補(bǔ)償彈簧以與調(diào)速器桿（4）相同的速率將小緩沖器補(bǔ)償活塞（21）返回到其正常居中位置。這將使先導(dǎo)閥柱塞（14）保持在其中心位置。
Increase in Load Again, assume the prime mover is running on-speed. The flyweights are in a vertical position and the pilot valve plunger is centered. When an increase in load occurs and the same fuel setting is maintained, an increase in load creates a decrease in speed. This generates the following sequence of governor movements: 1. As speed decreases, the centrifugal force of the flyweights (2) decreases and the opposing speeder spring (26) force is now greater than the centrifugal force of the flyweights (2). 2. The flyweights (2) tip inward, lowering the speeder rod (4) and the right end of the floating lever (18). 3. This lowers the pilot valve plunger (14) opening the control port in the rotating bushing (15). Pressure oil is released through the control port to the bottom side of the power piston (7).
Suction is thus applied to the chamber of the small compensation piston (20), lowering the left end of the floating lever (18). 7. The pvp (14) is lowered in turn, closing off the control port (16). 8. As sump oil flows through the needle valve (22) from the sump into the compensation piston assembly (20 and 21), the small dashpot compensation piston (21) is returned to its normal centered position by the compensation spring at the same rate as the speeder rod (4). This keeps the pilot valve plunger (14) in its centered position. 9. This keeps the control port in the pilot valve bushing (15) covered by the land on the pvp (14). 10. The output shaft (6) and power piston (7) movement is stopped in the new decrease fuel position required to run the prime mover at the selected speed setting with the decrease in load.
When a decrease in load occurs and the same fuel setting is maintained, a decrease in load creates an increase in speed. This generates the following sequence of movements: 1. As speed increases, the centrifugal force of the flyweights (2) increases, overcoming the opposing speeder spring force. 2. The flyweights (2) tip outward, raising the speeder rod (4) and the right end of the floating lever (18). 3. This raises the pilot valve plunger (pvp) (14), opening the control port in the rotating bushing (15). Oil is released from the bottom of the power piston (7) to sump. 4. The pressure oil acting on the top side of the power piston (7) forces it down and rotates the output shaft (6) in the decrease fuel direction. 5. Linkage from the output shaft (6) lowers the compensation adjusting lever (5) which pivots at the fulcrum (24), lifting up the large compensation piston (21).
